ESPN operates ESPN3 as a streaming video service. It is not available on any network channel offered by cable companies. Currently, ESPN3 is known as WatchESPN. Viewing the website requires a valid subscription to a cable service.

ESPN3 debuted as ESPN360.com with a focus on studio material. Over time, the content evolved to incorporate a greater number of live sporting events and more basic information than the flagship ESPN presentation. Typically, ESPN3 sporting events offer just limited commentary and minimal in-studio content. Additionally, ESPN3 delivers on-demand replays of recent sporting events that the ESPN family of networks has the rights to air.
